Stepper motor movement design based on FPGA

A stepper motor is an electro mechanical device that can convert electrical pulses to the axis of movement. The finding problem  in the movement of a stepper motor is  cannot respond to the clock signal directly because the motor windings require a clock (sequence) in the correct order. If the control signal given is not correct, the motor is not moving according to the specified precision. To answer these problems, it is necessary to move the stepper motor with a clock signal that works in real time. The research method is done by designing and testing the stepper motor movement in full stepp and half step with the direction of Clock Wise (CW) and Counter Clock Wise (CCW) movement. These are simulated by using FPGA Isim and implementation using a stepper motor. The results of several experiments have been carried out the stepper motor movement degree according to the input value entered,responding timely movement, and the direction of movement stepper motor

Single Axis Solar Panel Tracking Mount Using Stepper Motor and Accelerometer Positional Control

Optimal solar panel systems rotate to track the sun, as solar panels operate at their maximum potential when the panel plane is completely normal to the sun’s rays. These tracking systems often using two axes of movement. This project is to design a system that will allow a solar panel to track the sun using only one rotational axis, which saves energy and uses fewer parts. The system tracks the entire range of the sun\u27s motion and has positional feedback to allow control of the solar panel\u27s angle. The position of the tracking system is controllable via an external computer. The goal of this project is to construct a solar tracking device that accurately tracks the sun in order to maximize the energy output of the solar panel

Digital System Design - Use of Microcontroller

Embedded systems are today, widely deployed in just about every piece of machinery from toasters to spacecraft. Embedded system designers face many challenges. They are asked to produce increasingly complex systems using the latest technologies, but these technologies are changing faster than ever. They are asked to produce better quality designs with a shorter time-to-market. They are asked to implement increasingly complex functionality but more importantly to satisfy numerous other constraints. To achieve the current goals of design, the designer must be aware with such design constraints and more importantly, the factors that have a direct effect on them.One of the challenges facing embedded system designers is the selection of the optimum processor for the application in hand; single-purpose, general-purpose or application specific. Microcontrollers are one member of the family of the application specific processors.The book concentrates on the use of microcontroller as the embedded system?s processor, and how to use it in many embedded system applications. The book covers both the hardware and software aspects needed to design using microcontroller.The book is ideal for undergraduate students and also the engineers that are working in the field of digital system design.Contents• Preface;• Process design metrics;• A systems approach to digital system design;• Introduction to microcontrollers and microprocessors;• Instructions and Instruction sets;• Machine language and assembly language;• System memory; Timers, counters and watchdog timer;• Interfacing to local devices / peripherals;• Analogue data and the analogue I/O subsystem;• Multiprocessor communications;• Serial Communications and Network-based interfaces

A field programmable gate array based motion control platform

The expectations from motion control systems have been rising day by day. As the system becomes more complex, conventional motion control systems can not achieve to meet all the specifications with optimized results. This creates the need of re-designing the control platform in order to meet the new specifications. Field programmable gate arrays (FPGA) offer reconfigurable hardware, which would result in overcoming this re-designing issue. The hardware structure of the system can be reconfigured, even though the hardware is deployed. As the functionality is provided by the hardware, the performance is enhanced. The dedicated hardware also improves the power consumption. The board size also shrinks, as the discrete components can be implemented in FPGA. The shrinkage of the board size also lowers the cost. As a trade-off, FPGA programming is more complicated than software programming. The aim of this thesis is to create a level of abstraction in order to diminish the requirement of advanced hardware description language knowledge for implementing motion control algorithms on FPGA's. The hardware library is introduced which is specifically implemented for motion control purposes. In order to have a thorough motion control platform, other parts of the system like, user interface, kinematics calculations and trajectory generation, have been implemented as a software library. The control algorithms are tested, and the system is verified by experimenting on a parallel mechanism

Communication, mapping and navigational aspects for a free-ranging, automated guided vehicle.

Thesis (Ph.D.)-University of Natal, Durban, 1992.A free-ranging automated guided vehicle incorporating navigation and radio communication for use in a fully automated flexible manufacturing system has been developed. A vehicle, operating as a complete subsystem, was built and tested in an integrated control environment and proved to have promising results. various radio communication techniques are examined and the design and testing of a low cost, wireless, two way communication link is detailed. A novel, flexible infrared navigation technique was developed and incorporated into the AGV subsystem. Path planning and a flexible real time path modification system was formulated using an innovative program with an interpolative visual display unit and digitiser. Data transfer to and from the vehicles in a real time integrated system is covered. System integration for an free-ranging automatic guided vehicle is discussed covering aspects of communication, mapping and navigation. Specific needs for a free-ranging automatic guided vehicle, are presented. The unique design features of navigation and mapping outlined in this thesis has resulted in a low cost, free-ranging, autonomous automatic guided vehicle

Sinterização por aquecimento rápido com Loop temperatura/posição

Mestrado em Engenharia MecânicaDurante a sinterização de sistemas policristalinos ocorrem processos às partículas do material entre os quais densificação, engrossamento do grão, controlo da porosidade, segregação das partículas entre outros. Estes processos resultam num de três transportes de mecanismos condensação/evaporação na superfície, pela difusão nos limites do grão e pela difusão da látice. A microestrutura final pode ser modificada ao forçar um específico fenómeno a ser predominante sobre os restantes durante o processo de sinterização. Por exemplo, o processo de sinterização por aquecimento rápido representa um procedimento onde o perfil Temperatura-Tempo (T-t) é alterado rapidamente para atingir uma Temperatura (T) onde a densificação predominante sobre o crescimento do grão. Desta maneira é possível obter um tamanho de grão mínimo mantendo no entanto um grau de densificação elevado em materiais policristalinos. O trabalho aqui apresentado irá projectar e construir um dispositivo mecânico que permita introduzir amostras cerâmicas dentro de um forno com uma rampa de aquecimento controlada, enquanto tendo um feedback constante da posição e temperatura das amostras.The processes that occur during sintering of polycrystalline systems, are those of particle necking, densification, grain coarsening, porosity control, and segregation. These processes result from three mass transport mechanisms: surface condensation/evaporation, grain boundary diffusion, and lattice diffusion. The final microstructure can be varied by forcing a specific phenomenon to predominate over the others during the sintering process. For example, the fast-firing process represents a sintering procedure where the temperature– time (T–t) profile is altered to rapidly reach the T regime where densification dominates over grain growth. In this way, a small grain size can be maintained while still offering a high densification of polycrystalline materials. Therefore, the current work will design and build a mechanical device, to introduce ceramic samples into a furnace at a controlled ramp rate, with an instantaneous temperature/motion feedback loop
